CHURN.

SPECIFICATION forming part of Letters Patent- No. 535,230, dated March5, 18 95.

, Application filed July 11, 1894. Serial No. 517,226. (No model.)

T0 at whom it may concern.-

Be it known that 1, JOHN H. STEWART, a citizen of the United States,residing at Du Bois, in the county of Clearfield and State ofPennsylvania,have invented certain new and usefulImprovements in Chorus;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to whichit appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

Figure 1 is an elevation of a churn to which I have applied myimprovements. Fig. 2 isa horizontal section of the same just above thecover. Fig. 3 is a vertical section of the churn. Fig. 4. is a detailenlarged view of one of the bearings of the dasher. Fig. 5 is a detailview, partly broken away, hereinafter referred to. Fig. 6 is an enlargedview of one of the dashers.

The object of my invention is to provide a churn which will bring butterin the shortest possible period of time, with the minimum of exertion.

With such object in view my invention consists in the followingconstruction and combination of parts, which will first be fullydescribed in detail and the features of novelty contained therein thenspecifically set forth and claimed.

In the drawings-A represents a chu rn body which may be of any form orshape or construction suitable for the purpose. In the drawings I haveshown a keg or barrel form which gives good results.

B represents a series of vertical ribs formed upon the interior of thechurn.

O G is the cover made of two semicircular parts, both of which aredetachable.

D is the standard mounted upon one section of the cover, the top ofwhich carries bearings for the crank-shaft E.

F is the dasher shaft mounted upon a wooden conical bearing Gat thebottom of the shaft. The top extension H of the dasher shaft F has itsupper end inserted in a T- shaped bearing 1, which bearing has anopening at right angles to the opening which receives the shaft H, sothat it may be slipped upon the crank-shaft E and secured thereon by apin J, or other means of fastening the same.

In addition to the hearing I for the dashershaft is the bearing Kconsisting of two parts, one of which L is stationary and is secured bythe screw M to one-half of the cover, and the other, N, is movable,being slotted at 0, so that the part N may be moved in and out. Thescrew P secures the parts of the bearing together about the shaft F whenthe churn is operated. Both parts L and N of the bearing K are securedto one of the halves of the cover 0. I

Q is a transparency formed in the half of the cover which does not carrythe standard D, through which the condition of the contents of the churnmay be inspected.

R are pins secured to the inner sides of the churn-bodyA and projectabove thetop of the churn. The half of the cover 0 is provided withholes corresponding to the pins B so that the cover may be slipped downover the pins R and secured to the top of the churn by means of pins Swhich pass through the churn cover 0' and through the pins R. Theinterior of the pins R is hollow so that they perform the double officeof vent-tubes for the interior of the churn, and means of fastening thecover to the body. T are springs secured to the side of the churn, thefree ends of which are attached to the pins S for the purpose of holdingthe latter in place.

U are a series of dasher-blades secured to the dasher-shaft F at adownwardly projecting angle, the rear edges of which are provided withan inclined upwardly extending rib V.

The blades U are formed as shown in Fig. 6, being provided with adowel-pin W formed integral therewith and a solid rear extension X, bothof which are let into the dasher-shaft F at the angle shown.

To take out the dasher the cover G is taken off by removing the pins S.The pin J is then removed from the shaft E. The screw P is then loosenedand the part N of the bearing K slid outwardlyaway from the shaft F,when the latter with the dasher, may be removed from the churn. The partC of the cover which supports the standard is also removable.

IOC

After the butter has been brought, the butter may be washed in thechurn, and it may also be gathered by rotating the dasher back- Ward.The connection between the handle Y 5 and the dasher F is made by thebevel gear Z on shaft E, and the bevel pinion 2 on shaft F. Either oneof the bearings I or K may be dispensed with if desired, or both may beused.

I claim-- 10 In a churn the combination of a receptacle,

a rotary dasher mounted therein, a crankshaft,mechanism arranged betweenthe crankshaft and the dasher for rotating the same, and a couplingbearing for the dasher shaft located upon the cover and comprising twoparts, one of which is stationary and the other movable and working inthe stationary part by a sliding connection.

In testimony whereof I affix my signature in presence of two witnesses.
